TECHNOLOGICAL BACKGROUND

Molecular distillation, also known as high vacuum distillation or short path distillation, is a process of separation, purification and concentration of sensitive molecules from various compositions. The process is generally characterized by short term exposure of the composition to high temperatures, by high vacuum in the distillation column and a small distance between the evaporator and the condenser.

Molecular distillation has several advantages, for example avoiding issues of toxicity which are found in separation or purification techniques that employ solvents, minimizing losses due to thermal decomposition, and others.

Molecular distillation is suitable for purifying oils and fats from undesirable components. For example, molecular distillation is used for reducing toxins present in fish oil to levels considered to be safe, for enriching borage oil in γ-linolenic acid (GLA), for recovering tocopherols from soybean oil and for purifying diglycerides (DC) from vegetable oils and fats for a variety food applications.

Oil residues following molecular distillation processes can be used in the production of oil blends for a variety of applications in the food, cosmetics and other industries.

As shown in the following examples, blends according to the invention exhibit are more stable and resistant to oxidation, as measured by peroxide value (PV) after three weeks incubation at room temperature, compared to other blends. As shown in Example 2 (Table 3) a blend in accordance with the invention which contained fat residue resulting from molecular distillation of palm oil, blended with a residue of molecularly distilled rapeseed oil was substantially more stable, exhibiting no change in PV from baseline, than a blend of the same residue of molecularly distilled palm oil with non-distilled rapeseed oil, which exhibited a 30% increase in PV.

The results demonstrate again that blends which contain an oil residue resulting from molecular distillation of rapeseed oil, blended with a residue of molecularly distilled fat (palm kernel oil residue and palm oil residue) were more stable (no change in PV residue) than blends of the same rapeseed oil residue with non-distilled fats (palm kernel oil, 16% increase in PV and palm oil residue 220% increase of PV, respectively).

The present invention thus provides oil blends that are storage stable and are resistant to oxidation, in which the elevation in peroxide value within storage at mom temperature for at least 3 months is below 20% compared to the base value (time zero).

These blend all comprise at least one oil and at least one fat that underwent molecular distillation.

DESCRIPTION OF NON-LIMITING EXAMPLES Example 1: Reducing Diglycerides Levels Vegetable Oils Using Molecular Distillation

2000 gr rapeseed oil, palm oil and palm kernel oil (Florin—Netherland) containing 0.49% (w/w), 6.13% (w/w) and 0.61% (w/w) diglycerides, respectively, were processed using a pilot scale molecular distillation unit (VK 125-15, VTA company, Germany) with an evaporator having an inlet position and an outlet position. First the oils were fed (each separately) into a heated feed vessel at 50° C. and then pumped into a wiped film evaporator (degassing stage) to remove water and air residues (4.7-5 mbar and 145-185° C.). From the degassing stage the oil was pumped using a feed rate of about 12 kg/hr into the short path distillation unit with the evaporator having an inlet position and an outlet position. Distillation parameters are summarized in Table 1.

Residue fraction and distillate fraction were collected. The weight percentage of the distillate resulting from the molecular distillation was calculated out of the initial amount and is presented in Table 1.

As shown in Table 2 the molecular distillation resulted in oil and fat residues with significantly reduced diglycerides (DG) content compared the DG in the oil before distillation.

The stability of the above mentioned individual distilled oils and fats is significantly lower in comparison with the corresponding non-distilled oil or fat.

Example 2: Stability of Molecularly Distilled Fat (Palm Oil) and Non-Distilled Oil Blend VS Molecularly Distilled Fat and Molecularly Distilled Oil Blend

Three aliquots, each of 30 gr of palm oil residue following molecular distillation (Example 1), were mixed each with one of the following oils (as described in Example 1):

-   -   1. 30 gr rapeseed oil (Florin—Netherland)     -   2. 30 gr rapeseed oil residue following molecular distillation         (483-42-17)     -   3. 30 gr of palm kernel oil residue following molecular         distillation (483-43-11)

Stability of all three blends was tested at baseline (t=0), and following incubation at room temperature for 3 weeks, using peroxide value (PV) measurements. The results of the stability test are summarized in Table 3 and demonstrate that a blend which contains a fat residue resulting from molecular distillation (palm oil residue) blended with a residue of molecularly distilled oil (rapeseed oil) is substantially more stable (no change in PV) than when blended with a non-distilled rapeseed oil (30% increase in PV). Surprisingly, the palm oil residue blended with rapeseed oil residue (no change in PV) was also more stable than a blend of palm oil (a fat) residue blended with palm kernel oil residue (20% increment in PV).

Example 3: Stability of Different Blends Containing Rapeseed Oil Residue Following Molecular Distillation

Four aliquots, each of 30 gr of rapeseed oil residue following molecular distillation (Example 1), were mixed each with one of the following oils (as described in Example 1):

-   -   1. 30 gr palm kernel oil (Florin—Netherland)     -   2. 30 gr palm kernel oil residue following molecular         distillation (483-43-11)     -   3. 30 gr of palm oil (Florin—Netherland)     -   4. 30 gr of palm oil residue following molecular distillation         (483-44-11)

Stability of all four blends was tested at baseline (t=0), following one week incubation at accelerated conditions of 40° C. using peroxide value (PV) measurements. The results of the stability test are summarized in Table 4 and demonstrate again that blends (483-49-1 and 483-49-2) which contain an oil residue resulting from molecular distillation (rapeseed oil residue) blended with a residue of molecularly distilled fat (palm kernel oil residue and palm oil residue, respectively) were more stable (no change in PV residue) than blends (483-49-9 and 483-49-11) of the rapeseed oil residue with non-distilled fats (palm kernel oil, 16% increase in PV and palm oil residue, 220% increase of PV, respectively).
